Walker 211-2102 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Porsche

Walker Products 211-2102 is a sensor-only engine coolant temperature sensor built to report real-time coolant temperature to the ECM. For Porsche 911, Boxster, and Cayman applications, it supports accurate fuel delivery, ignition timing, cold-start enrichment, and cooling fan control.

Walker Sensor Only parts are focused on direct replacement fitment and OE-style signal accuracy. This line is built for technicians and owners who need a straightforward sensor replacement without added harness components.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Blade terminal type with 2 terminals
• Female circle connector shape
• Sensor only design; wiring harness not included
• Engineered to match OE resistance values, thermal response, and signal output
• Heat-resistant construction for coolant exposure, vibration, and temperature swings
• Direct-fit replacement for factory-style installation

Detailed Description

Walker 211-2102 is designed to replace a failed coolant temperature sensor and restore accurate temperature feedback to the engine control module. That signal is critical for proper engine management, especially during cold starts and under changing operating temperatures. This part cross-references OE-style numbers such as 1TS1134 and 5S12429 for the same application.

Compatible With Porsche 911, Porsche Boxster, and Porsche Cayman applications from 2009 through 2013, this sensor is a practical replacement when the original unit is causing drivability concerns or a check engine light. The 211-2102 is built to integrate with factory systems and maintain consistent signal behavior.

What It Helps Solve

• Incorrect coolant temperature readings
• Hard starting when the engine is cold
• Rough idle caused by inaccurate ECM temperature input
• Cooling fan operation issues tied to sensor data
• Check engine light related to coolant temperature sensor faults

Installation Notes and Tips

Verify connector shape, terminal type, and terminal count before installation. This sensor uses a female circle connector with blade terminals and does not include a wiring harness. Confirm the vehicle application against the listed Porsche 911, Boxster, and Cayman fitment before replacement.
